.Ficus burtt‐davyi is a shrub or small tree found in the south and east of South Africa. Based on studies carried out in an area where the plant grows mainly as a rock‐splitter, we first describe the nature and timing of the fruit resources it offers to potential dispersal agents, and then the animals that feed on the fruits. The figs are eaten by a diverse avian disperser assemblage, although just two species comprised about half of the recorded visits to the trees. Germination trials with seeds defecated by the birds found that they germinated more quickly than control seeds. Small terrestrial mammals and ants were also found to have a role in fig seed dispersal which may be disproportionate to the number of seeds they transport.
